Wayne attended Vashon High School in north St. Louis and graduated in the 2016 class. Wayne played football at Vashon.
Wayne's former coach, Kenneth Cooper, had been a mentor to Wayne and kept in touch with him until recently.
"He had a promising career. I watched him play a few games. He was the happiest kid I ever coached," Cooper said. "He told me, 'I'm going to school, I got a scholarship!' And I was happy for him. He went there to better his life and this is what happened."
The crime happened about midnight Tuesday night into Wednesday morning on the Grambling State campus. Investigators said Wayne shot and killed fellow Grambling State students Earl Andrews and Monquiarious Caldwell. Both victims were 23-years-old and from Farmerville, about 30 miles from the university.
Authorities said Wayne and the two victims knew each other "to some extent" and that Wayne shot Andrews during a fight and then Caldwell, who was coming to help Andrews. Both victims died at the scene.
Wayne was taken into custody about 8:30 p.m. Thursday. Police said he turned himself in after learning a warrant had been issued for his arrest.
